The target is now in the test-stand, and by next week Tuesday, it should go in the Hotcell.

The target was tested in the Test-stand.  The EE was inspected and a small amount of deposit was discovered after the test (the same stuff was found on Ta#36),  see attachment #1.  The samples were collected and will be analyzed through SEM/EDX/XRD.

The EE and the common plate were cleaned with methanol and were assembled back.

The target is ready to go in the Hotcell tomorrow, June 05.

 Monday, November 05, 2012, 16:42

The deposits on the EE and CC were analyzed using XRD

On the EE, it was mainly copper hydroxide nitrate, Cu2(OH)3(NO3). (see attachment #2)

On the CE, it was mainly tantalum, Ta. (see attachment #3)

Two targets of Nb-HP-SIS are complete and ready to be installed in the heat shields:

-----------------------------------------------------------------------------------

Target oven w.o# 38817-1:

inner diameter: left = 18.27mm, right = 18.25mm.

Filled with 400 foils Nb (16pk, 5 foils/pk).  

Discs spec: 18.65mm/14.65mm, thickness = 0.022mm  

Total mass + Ta-wire = 22.74g

Total length = 4.5cm

Rn foil inserted for ionization.  (0.1mm, 0.004", 1cm x 1cm)  

------------------------------------------------------------------------------------

Wednesday, July 06, 2011, 14:35: Salts were added and tested in test-stand last 2 weeks.

First batch of UO2/C mixture of carbonization (Stock# 2011_A):   

UO2 used = 50.120g (left overs + container = 411.23g)

C(grv) used = 10.653g (or 21.25% w/w)

Mass of organics = 4.842g (or 9.66% w/w) 

Mass of dried cast = 47.420g 

Waste collected in jar = 18.195g (including UO2, C and Org) 

Waste accountable for UO2 = 12.57g

The carbonization process started from May 26 to June 4 (9 days).  

See attachment #1 and #2 for the striptools during the UO2/C carbonization

Total Mass UC2 flakes = 35.310g 

 Fri Jun 17 11:56:15 2011

Attempted to make the second batch of UO2/C mixture of carbonization on June 13, but it failed.  The milling jar gasket seal partially came out during the high speed milling.  As a result, the UO2/C mixture squirted out and contaminated the planetary mill (See attachment #3 & #4).  RPG and all other groups were informed.  The planetary mill and the lab were properly cleaned up (see attachment #5), no activities were found after the cleaning.  Attachments #6, #7, #8 are some of the discussion about the UO2 spill.  

All the UO2 taken out from the container (50.23g) is accountable for waste.  

 June 28, 2011 - Re-making 2nd batch of UO2/C mixture was successful.  

Stock#2011_B:

UO2 used = 50.29g

C(grv) used = 10.0g 

Mass of Organics = 4.84g 

Mass of Dried green = 71.96g (the cast was let dry over night <24hrs due to time restriction.  It might not be completely dried as a result of such heavy mass remained.  However, the UO2 waste was very minimum, <5.0g) 

Total Mass UC2 flakes = 56.853g 

Details about Ta Hp surface, w.o#38295-4 (spare):

This target was built as a spare.

Note: Left side target arm replaced, Nov 18, 2010.  Weld prep on centre block misaligned.  (Marik has more details about this).

Packs of Ta foils were prepared by JW. 

Target was filled with 400 of 0.025mm foils (25 foils/pk) in 4.0cm length. 

Total Mass of 16 packs of Ta foils + Ta wires = 42.70g.  

See attachment#1 for the measurement.
